1989 Ford Bronco V8 Four Wheel Drive Automatic 65,000 miles

I have a 89 bronco full size and it has a lack of power when I floor my bronco it dose not spin tires it takes its time getting up to speed I have done the tune up and that helped but did not fix the problem. I have also replaced the cathlatic converters and that did not help. So if anyone has a sugestion do not hesitate to leave me a messange?

Lack of acceleration, chugging, hesitating, jerking, bogging, misfiring etc. Could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note: If it doesn't apply disregard it
